WHIEL FOR SPINNING-FRAMES.

Specification of Letters Patent.

Application filed March 25, 1910. Serial No. 551,435.

To all whom it may concern:

Be it known that I, "WILLIAM ST. PETER, a citizen of the United States,residing at Manchester, in the county of Hillsboro and State of NewHampshire, have invented a new and useful Improvement in Vhirls forSpinning-Frames, of which the following is a specification.

My invention relates to all spinningframes, whether of the cap, ring,twister or other types, wherein the whirl is of that type which isprovided with a tube-spindle inas distinguish ed from that type whereinthere is no tubespindle, as shown in the patent to Ashworth, Feb. 14,1905, Serial Number 7 82,535, in Class 1lS-Spinning, spindles andappurtenances; and wherein the whirl is provided with a lug or lugs,usually two, integral parts of the whirl at its base, whereon the bobbinsets in actual spinning operation, the bobbin being provided withcorresponding slots to fit over the lugs when the bobbin is seated.These lugs, usually directly opposing each other, and in alinement withthe spindle of the whirl, are intended to prevent rotary movement of thebobbin upon the whirl in the spinning operation, but in actual practicethey frequently fail to effect this purpose on account of the jumping ofthe bobbin upon the whirl. This jumping of the bobbin, not only causesloose and imperfect winding and consequent frequent breaking of the yarnor thread, but very materially shortens the life of the bobbin, and alsoresults in great inconvenience, loss of time, waste of yarn or thread,and often, imperfections in weaving.

My invention is intended to overcome these difliculties in connectionwith the operation of the type of whirl above referred to, which has atube-spindle, and which is now used in the mills of New England atleast, to the exclusion of all other types of whirls for both cotton andworsted spinning by providing comparatively inexpensive, and at the sametime thoroughly efficient means to hold the bobbin in its normalposition upon the whirl, during the spinning process,consistingpreferably of two straight, flat pieces of spring steel, ofapproximately one-half the length of the spindle of the whirl, of properwidth and thickness,which, with one end of each securely fastened to thespindle, and in alinement therewith, with their free ends terminatingsubstantially at the base of the spindle of the whirl, act as frictionsprings to hold the bobbin in normal position while in operation, thecentrifugal force exerted by the high rate of revolution of the whirl,causing the springs by direct pressure upon the inner wall of the bobbinto securely hold the bobbin against both the rotary and jumpingmovements referred to.

The type of whirl without an integral tube-spindle has, I am creditablyinformed, been tried and discarded as useless, for three very importantand conclusive reasons: 1st, because of the oscillation and insecurityof the mandrel and the bobbin upon the whirl,

except when the machinery runs at its normal high speed, insuring fullengagement of the openings in the arms of the mandrel with the pinsprojecting-from the inner wall of the whirl. 2nd, because thecentrifugal force, relied upon to secure the mandrel upon the whirlbase, forces the lubricating oil upward on the spindle, and outwardbetween the arms of the mandrel and thenceupon the bobbin and yarn,causing more waste than under the old method. 3rd, because of thefrequent clogging of the man drel by the flying waste, which at theusual high speed of the machinery, is thrown off by the rapidlyrevolving whirl.

The nature of my invention is further hereinafter described and isillustrated in the accompanying drawing in which similar letters ofreference indicate corresponding parts.

Figure 1 is a view in elevation of a whirl such as is used in worstedspinning, without the lugs now in use, and with my invention appliedthereto, the springs in the position inactive while the whirl is atrest. Fig. 2 is a sectional view of the whirl in the same position as inFig. 1, with a bobbin seated in outline upon the whirl, and the springactively pressing against the bobbin wall by the action of centrifugalforce. Figs. 3 and 4c are longitudinal views of the spring showing thecomparative thickness and width of the steel pieces adapted to the Whirlused in worsted spinning.

a is a whirl such as is now in use in worsted spinning, of actual size,except that the spindle thereof is somewhat shortened for the purpose ofthis drawing, 6 is the base of whirl upon which the bobbin is seated inoperation, 0 is my invention, showing at d the comparative point ofattachment to whirl. spindle, and at 6 its termination in the recess ofbase of whirl, and f is a bobbin outlined in its position upon thewhirl.

As more clearly shown in Figs. 3 and 4t it will be seen that the spring0 is formed of a comparatively thin sheet material having perfectlystraight dimensions. This spring is secured to the whirl spindle at Iand is adapted to lie parallel with and flat against the spindle, exceptwhen under the action of centrifugal force it is caused to buckle orotherwise move from its normal perpendicular position.

While I have chosen to illustrate my invention in connection with aworsted whirl having an integral tube-spindle it will, of course, beunderstood that the spring is applicable to any similar whirl now in usefor spinning woolen, cotton, worsted or other yarn or thread, thesprings proving efficient for warp, filling and all fine work as well asfor twisting and coarse work.

My spring may be employed eiiiciently upon the old whirl, without theexpense of the removal of the two lugs, by placing a "asher on spindleresting upon the lugs, upon which to seat the bobbin.

IVith the use of whirls provided with my springs, I have found itpracticable to employ the bobbins which have been thrown aside asuseless, on account of the breaking away of their entire bases to thefull depth of the slots; and it has been proved in actual operation thatthese old bobbins, with the perfect winding of the yarn secured by theuse of my device, are equally eflicient in the subsequent weavingoperation.

In actual operation upon a spinning frame the springs are, bycentrifugal force exerted, pushed outwardly against the inner wall ofthe bobbin. The higher the machinery is speeded, the greater thepressure of the springs.

I am now aware that prior to my invention, frictional means had beendevised intended to hold a bobbin upon the whirl during the windingoperation, as in Sullivan, May 12, 1903, Serial Number 728,042, and inthe case of Ashworth, above referred to, but neither of these devicescan be successfully applied to the particular form of whirl now almostuniversally in use, the Ashworth device being specially limited towhirls without integral tube-spindles. In view of the state of the artas disclosed by these two cases, I do not claim the combination offrictional means in spinning whirls to hold the bobbin thereon inoperation broadly; neither do I claim the invention of a newmanufacture, but rather the perfection of an old device so as to make itmore valuable, in terms as follows.

I claim:

1. A spinning whirl of the type provided with an integral tube, having astraight, fiat, thin, narrow piece of resilient metal attached at one ofits ends to said tube, and disposed in alinement therewith, with itsfree end extended into a shallow depression in the whirl, whereby abobbin is held in operative position upon the whirl by the pressure ofsaid piece of metal upon the inner wall of the bobbin, exerted wholly bycentrifugal force, substantially as described.

2. In combination with a spinning whirl of the type provided with anintegral tube, a straight, flat, thin, narrow piece of resilient metal,which, attached at one of its ends to the whirl tube, with its free endextending downwardly in alinement with the tube, into a shallowdepression in the whirl, is pressed outwardly wholly by the centrifugalforce generated by the revolution of the whirl, and thereby holds abobbin in operative position upon the whirl, substantially as described.

3. In combination with a spinning whirl of the type provided with anintegral. tube, a straight, fiat, thin piece of steel, which, fastenedat one of its ends to the whirl tube, with its free end extendingdownwardly in alinement with the tube into a shallow depression in thewhirl, exerts no independent pressure, but is pressed outwardly againstthe inner wall of the bobbin wholly by centrifugal force, and therebyholds a bobbin in operative position upon the whirl, substantially asdescribed.

WILLIAM ST. PETER.
